# Suburb
## Overview
A **suburb** is a residential area on the edge of a city — close enough to access urban amenities but physically separate from the city center. Suburbs are defined by their relationship to the city: they exist because the city exists, and their identity derives from proximity to it.
## Etymology
From Old French *suburbe*, from Latin *suburbium* ('the area near a city'), composed of *sub-* ('below, near, close to') and *urbs* (genitive *urbis*, 'city'). The further etymology of *urbs* is uncertain.
## Roman Suburbia
In Roman usage, *suburbium* designated the zone immediately outside the city walls. This area had a distinct character:
- **Villas**: wealthy Romans built country houses (*villae suburbanae*) in the *suburbium*, escaping urban density while remaining close to the city's political, economic, and social life - **Gardens and farms**: the *suburbium* provided fresh produce for city markets - **Cemeteries**: Roman law prohibited burial within the city walls, so tombs lined the roads leading out of the city — the Via Appia's famous catacombs were suburban - **Industry**: activities too noisy or polluting for the city (tanning, pottery kilns) were pushed to the outskirts
This mix of wealth and nuisance, retreat and marginality, has characterized suburbs throughout history.
## The Urbs Family
Latin *urbs* ('city') generated a small but culturally significant English word family:
- **Urban**: of or relating to the city - **Urbane**: polished, sophisticated — originally 'characteristic of city dwellers,' who were considered more refined than rural people - **Urbanize**: to make urban, to convert rural land to city use - **Suburban**: of the suburb - **Suburbia**: suburbs collectively, often with a pejorative connotation - **Exurb**: *ex-* + *urbs* — an area beyond the suburbs, coined in 1955
The contrast between *urbanus* ('of the city, refined') and *rusticus* ('of the countryside, rough') shaped Latin and then European cultural assumptions for centuries. 'Urban' became a synonym for civilization; 'rural' for simplicity or backwardness. The suburb occupies the contested territory between them.
## Modern Suburbs
The modern suburb as a mass phenomenon dates to the mid-19th century, when railways allowed middle-class workers to live outside cities while commuting to urban jobs. The pattern accelerated dramatically after World War II, particularly in the United States, where highway construction, Federal Housing Administration loans, and the automobile enabled rapid suburban development.
Suburbs have been both celebrated (as havens of space, safety, and family life) and criticized (as environmentally wasteful, socially isolating, and architecturally monotonous). The tension is encoded in the word itself: a suburb is defined by what it is not (the city) rather than by what it is.
## Related Forms
The family includes **suburban** (adjective), **suburbia** (collective noun, often pejorative), **suburbanite** (a suburb resident), **suburbanize** (to develop as suburbs), and **exurb** (a district beyond the suburbs).
